The nonlinear equivalences of both finite and infinite zero structures of linear systems have been well understood for single input single output systems and have found many applications in nonlinear control theory. The extensions of these notions to multiple input multiple output systems have proven to be highly sophisticated. In this paper, we propose constructive algorithms for decomposing a no...

Publication Year: 2011, Page(s):254 - 264

| |PDF (866 KB) | HTML

We discuss N-Skart, a nonsequential procedure designed to deliver a confidence interval (CI) for the steady-state mean of a simulation output process when the user supplies a single simulation-generated time series of arbitrary size and specifies the required coverage probability for a CI based on that data set. N-Skart is a variant of the method of batch means that exploits separate adjustments t... View full abstract»

• ### Iterative Encoder-Controller Design for Feedback Control Over Noisy Channels

Publication Year: 2011, Page(s):265 - 278

| |PDF (738 KB) | HTML

We study a closed-loop control system with state feedback transmitted over a noisy discrete memoryless channel. With the objective to minimize the expected linear quadratic cost over a finite horizon, we propose a joint design of the sensor measurement quantization, channel error protection, and controller actuation. It is argued that despite that this encoder-controller optimization problem is kn... View full abstract»

• ### Distributed Consensus With Limited Communication Data Rate

Publication Year: 2011, Page(s):279 - 292
Cited by:  Papers (229)
| |PDF (789 KB) | HTML

Communication data rate and energy constraints are important factors which have to be considered when investigating distributed coordination of multi-agent networks. Although many proposed average-consensus protocols are available, a fundamental theoretic problem remains open, namely, how many bits of information are necessary for each pair of adjacent agents to exchange at each time step to ensur...

• ### On Lossless Approximations, the Fluctuation- Dissipation Theorem, and Limitations of Measurements

Publication Year: 2011, Page(s):293 - 308
Cited by:  Papers (14)
| |PDF (542 KB) | HTML

In this paper, we take a control-theoretic approach to answering some standard questions in statistical mechanics, and use the results to derive limitations of classical measurements. A central problem is the relation between systems which appear macroscopically dissipative but are microscopically lossless. We show that a linear system is dissipative if, and only if, it can be approximated by a li... View full abstract»

This paper considers a coherent H∞ control problem for a class of linear quantum systems which can be defined by complex quantum stochastic differential equations in terms of annihilation operators only. For this class of quantum systems, a solution to the H∞ control problem can be obtained in terms of a pair of complex algebraic Riccati equations. In addition, ... View full abstract»

| |PDF (569 KB) | HTML

This paper investigates sufficient conditions for the convergence to zero of the trajectories of linear switched systems. We provide a collection of results that use weak dwell-time, dwell-time, strong dwell-time, permanent and persistent activation hypothesis. The obtained results are shown to be tight by counterexample. Finally, we apply our result to the three-cell converter. View full abstract»

| |PDF (643 KB) | HTML

Many small electronic devices such as cell phones and wireless sensors have restrictive memory space, computing power, and battery. The pervasive applications of these devices in industry, military, and our daily lives require simple policies that are easy to implement, and can be executed in a reasonably short time. The Markov decision process (MDP) provides a general framework for these policy o... View full abstract»

In this article, we investigate the problem of simultaneously steering an uncountable family of finite-dimensional time-varying linear systems with the same control signal. This class of control problems motivates further research in the new subject of control theory called Ensemble Control, a notion coming from the study of complex spin dynamics in nuclear magnetic resonance spectroscopy and imag...

• ### Global Inverse Optimal Control With Guaranteed Convergence Rates of Input Affine Nonlinear Systems

Publication Year: 2011, Page(s):358 - 369
Cited by:  Papers (32)
| |PDF (596 KB) | HTML

In earlier works, global inverse optimal controllers were proposed for input affine nonlinear systems with given control Lyapunov functions. However, these controllers do not provide information about the convergence rates. If the systems have local homogeneous approximations, we can employ homogeneous controllers, which locally asymptotically stabilize the origin and specify the convergence rates...

Publication Year: 2011, Page(s):370 - 375
Cited by:  Papers (91)
| |PDF (231 KB) | HTML

This work studies a predictive networked control scheme in which packets containing optimizing sequences of control inputs are sent over an unreliable communication network affected by data-loss. We show that, provided the number of consecutive packet losses is bounded, input-to-state stability can be ensured by appropriate choice of design parameters. Our results apply to the general case of cons... View full abstract»

This technical note shows that the stationary distribution for the covariance of Kalman filtering with intermittent observations exists under mild conditions for a very general class of packet dropping models (semi-Markov chain). These results are proved using the geometric properties of Riccati recursions with respect to a particular Riemannian distance. Moreover, the Riemannian mean induced by t... View full abstract»

Sufficient conditions are given for the stability of linear switched systems with dwell time and with polytopic type parameter uncertainty. A Lyapunov function, in quadratic form, which is non-increasing at the switching instants is assigned to each subsystem. During the dwell time, this function varies piecewise linearly in time after switching occurs. It becomes time invariant afterwards. This f... View full abstract»

In this note, a filtered repetitive controller (FRC) is designed to compensate for periodic disturbances in a class of nonlinear systems. First, a new model of periodic disturbances is proposed. By this model, the FRC is designed and the resulting closed-loop error dynamics are analyzed with the help of a Lyapunov-Krasovskii functional. Finally the method is applied to periodic disturbance rejecti... View full abstract»

In a proportional task allocation problem, it is desired for robotic agents to have equal duty to capability ratios. Here, this problem is addressed as a combination of deployment and consensus problems. Tasks occur in a convex region and each task is assigned to its nearest agent. Agents are deployed on this area in order to reach consensus over the value of their duty to capability ratio. A dist... View full abstract»

This technical note is concerned with exponential stability analysis of linear time-varying systems represented by the second-order vector differential equations with the singular leading coefficient matrix. Using bounding techniques on the trajectories of the linear time-varying systems, the stability problem of the time-varying systems is transformed to that of the time-invariant systems and a n...

| |PDF (298 KB) | HTML

In the stochastic formulation of chemical kinetics, the differential equation that describes the time evolution of the lower-order statistical moments for the number of molecules of the different species involved, is generally not closed, in the sense that the right-hand side of this equation depends on higher-order moments. Recent work has proposed a moment closure technique based on derivative-m... View full abstract»

This technical note presents a global finite-time observer design for a class of systems with Lipschitz nonlinearity. By applying a finite-time stability theorem and a careful selection of the homogeneity powers and weights, the problem of global and finite-time stable observers is studied. An observer design procedure is given and a numerical example is provided to illustrate the design method. View full abstract»

In recent years, singular hybrid systems have received considerable attention. However, few results are concerned with stability of singular hybrid stochastic systems. Based on a stability result for singular hybrid systems, this note studies mean-square stability of singular hybrid stochastic systems. It is found that the diffusions and the Markov chain may play important roles in system analysis... View full abstract»
